I've got the same trans in my 2019 2500 and from what I've read over the years, it seems to hold up fine. Not many problems with that Trans or any other offerings from the Big 3. Live others said, the key is maintenance.

Ron, you were one of the reasons that I changed up from the Tundra since we were both in the same boat.

Anything “can” be done but it won’t be practical or cheap. There are conversion kits and physically they are about the same length. But if you’re going to go through the trouble of building a frankentruck, just swap an Allison into it.
Or a 6 speed manual if it’s a dedicated tow rig.
68re would not be the top of the list if I was building a truck. Better options available.

There didn’t used to be, too many computers involved between the 6.7 and 68RFE. Maybe someone has figured it out by now, The 5.9 would be great with a six speed.

From what I've read, while you can't swap to the 68R, you can bring your 48 up to 68 standards with some heavy duty aftermarket parts

I'm pretty sure the aftermarket parts can make a 48 exceed a 68. Having said that our 05 dodge with its aftermarket 48 gave up the ghost a few months ago and got ditched for a standard mopar rebuild.

Having said that I would take a stock 68 over a pos 48 any day.

Those of you that are “pretty sure” you can’t do it are mistaken.
And yes you can build a 48 to hold insane power, same as you can build a 68 to do the same.
What you can’t do is add 2 more gears to the 48, which is a real hinderance to the Cummins performance when towing, with only 4 gears.
